Q

Stress incontinence surgical management:

A

Urethral bulking agents
• Benefits – no incision, low risk, best for intrinsic sphincter deficiency,
• Risks – highest recurrence, need for repeat, urethral injury, need for self catheterisation
Transvaginal mid urethral tape
• Benefits – gold standard for SUI with 90% success rates
• Risks – infection, bleeding, bowel/ureteric injury, de novo detrusor overactivity, voiding dysfunction, dyspareunia, chronic UTI, mesh erosion, fistula, thigh pain (transobturator only)
Burch colposuspension (the bladder neck is lifted, vagina is attached to the ligament behind the pubic bone with sutures and this will lift and support your bladder neck which helps it resist increases in abdominal pressure)
• Benefits – avoid further vaginal incision, good continence rates (90% at one year, 70% at 5 years), no mesh risks
• Risks – as above without mesh risks, risk of posterior vaginal wall prolapse due to angulation of vagina.

Q

Pelvic organ prolapse management:

A

o Lifestyle advice
 avoid heavy lifting
 avoid straining (give laxitives)
 weight loss
o Conservative
 pelvic floor muscle physiotherapy – may improve symptoms or early stage prolapse but does not alter prolapse severity
 Ovestin cream for vulvovaginal atrophy and dyspareunia
 Offer pessary
• Type - ring for anterior prolapse, space occupying (shelf or cube) for vault prolapse
• Risks include erosion, infection, discomfort, failure.
o Surgical options
 Anterior repair + SSF
 Abdominal (laparoscopic or open) sacrocolpopexy/hystopexy
 Colpocleisis not appropriate given patient wants to continue having intercourse

Q

Overactive bladder management:

A

 Conservative – avoid bladder irritants, 1.5L fluid balance, bladder retraining, biofeedback
 Medical
• Anticholinergics - oxybutynin or solifenacin – side effects include dry eyes/mouth, constipation, long term risk of dementia. Aim for short term use only.
• B3 adrenoceptor agonist - Mirabigron – can cause hypertension, renal and liver impairment
 Electrical
• No routinely recommended
• TENS/PTNS - offer last resort
 Surgical – botox, clam cystoplasty, detrusor myomectomy, ileal conduit

Q

Anterior Repair Steps:

A

• Consent
o Bleeding
o Infection
o Damage to bladder
o Dysparunia, vaginal narrowing
o Recurrence
o Voiding dysfunction
o Buttock ache
• Steps of Anterior Repair
o Pre-Op
 Consent
 Anaesthetic assessment
 WHO sign in
o Intra op
 Anaesthetic
 Position in dorsal lithotomy
 Check allergies and antibiotics (not routinely required)
 VTE prophylaxis
 Prep and drape
 WHO Time Out
 Do not place IDC at start of procedure
 EUA to reassess POP-Q score now fully relaxed with anaethetic
 Place Allis forcep on anterior vaginal wall in the midline 1-2cm from urethral meatus
 Place second Allis forcep on the anterior vaginal wall in the midline as proximal as possible beyond the most distal portion of the prolapse
 Assistance to hold allis forceps superior and inferiorly to put vaginal mucosa under tension
 Infiltrate local anaesthetic in the midline to elevate mucosa off underlying fascia and extend infiltration laterally on each side
 Use scalpel to cut vaginal mucosa longitudinally between each allis forcep
 Place new allis forceps on free edge of vaginal mucosa on one side to elevate it off the fascia. Dissect the mucosa off the fascia (can be blunt with small gauze wrapped over a finger if no previous surgery or may need to be blunt with fine tissue forceps angled towards the mucosa). Repeat on opposite side until paravaginal fasica is reached.
 Plicate the fascia using interrupted 2.0 pDS leaving each suture untied and long and attached to a small artery clamp
 Sequentially tie off each suture starting with most proximal in the vagina.
 Ensure haemostasis
 Assess need to trim vaginal mucosa. Do not perform excessively to avoid undue tensions on repair increasing risk of breakdown and vaginal narrowing
 Repair vaginal mucosa continuously with 2.0 vicryl
 IDC + pack
o Postop
 Document
 discuss follow-up: analgesia, pelvic rest 4-6 weeks, ovestin cream, no heavy lifting 4-6 weeks, clinic 4-6 weeks

  1. Urge-predominant mixed incontinence or type is unclear
  2. Symptoms suggestive of voiding dysfunction
  3. Anterior or apical prolapse
  4. A history of previous surgery for stress incontinence
17
Q

Management of urinary incontinence

A

Lifestyle Weight loss

  • Offer dietician referral
  • Can improve UI

Fluid intake
- Reduce to 1-1.5L/day
Avoid tea, coffee, alcohol – can irritate bladder
If nocturia an issue, reduce fluids in the evening

Bladder retraining Usually done through PT
Aim to pass more urine less frequently
Bladder drill outcomes:
· 90% continent and 83.3% symptom free after 6/12 (compared to 23.2% in control group)
· 40% relapse within 3y

Pelvic floor exercises
Increases strength of pelvic floor muscles, leading to improved control of urine leakage

Topical oestrogen
· May improve atrophy and increase sensory threshold of the bladder

Medications
Review current medications – some meds increase urine production, e.g. diuretics
- Sedatives can worsen OAB symptoms
Anticholinergics (oxybutynin)
- reduce OAB symptoms by up to 75%
- Inhibit detrusor contraction
- Side effects – dry mouth, constipation, blurred vision
- Concern around impact on cognitive ability, try use for short term only (1y then break)
Mirabegron (Betmida) beta 3 –adrenoreceptor agonist

18
Q

Treatment of VIN:

A

Surgical e.g. wide local excision
 Best for those at increased risk of invasive disease (previous VIN or vulvar carcinoma, immunosuppression, tobacco use, age >45yrs, history of lichen sclerosus)
 Recommended in differentiated type at 30% risk of progression to cancer
 Provides histological specimen, curative intent
Ablative therapy e.g. laser vaporisation
 Young women, multifocal disease lesions involving clitoris, urethra, anus or vaginal introitus (excision –> dyspareunia)
 Cosmetic advantage as superficial, results in less dyspareunia (if sexually active)
Pharmacological therapy e.g. Imiquimod
 Topical treatment - can apply at home
 Avoids surgery - option for medically co-morbid patients who are poor surgical candidates
 Useful if multi-focal as above
 Consider for recurrent lesions to reduce anatomical distortion (preserves anatomy) with multiple excisional procedures

19
Q

Symptomatic prolapse

A

Management
1.Conservative
a. PFMT with PT
b. Ovestin cream twice weekly
2. Medical
a. Pessary – needs to be reviewed at least every 12 months and must use ovestin cream twice weekly
3. Surgical
a. Anterior repair + vaginal hysterectomy +/- SSF if indicated
b. Anterior repair + sacrohysteropexy if wanting uterine conservation
c. Briefly discuss risks with vaginal surgery

new incontinence, bleeding,
infection, damage to surrounding structures, recurrence

20
Q

Menopause well woman check

A

Lipids, Cholesterol, HbA1c, yearly BP check
DEXA scan, weight bearing exercise, Vit D and calcium supplementation
Mammogram 45 to 69 every two years
Cervical smear three-yearly from age 25 to age 69.

21
Q

Stress incontinence management

A
Medical:
1. Knob pessary
Surgical:
1. Urethral bulking
2. Mid urethral sling (TVT, rectus fascial sling) – risk with mesh discussion
3. Burch Colposuspension
22
Q

Overactive bladder

A

Medical:
1. Commence on oxybutynin - discuss side effects (dry mouth, postural hypotension
a. If oxybutynin unsuccessful, solefenacin
b. Mirabegron
2. PT nerve stimulation
Surgical
3. Bladder botox – risks with this including intermittent self-cathetrisation
4. Sacral neuromodulation

23
Q

Paget’s disease of the vulva

A

pruritic rash - velvety red with dotted white islands
Extramammary pagets disease is an intra epithelial adenocarcinoma that accounts for less than one percent of all vulvar malignancies

Generally affects those in 60-70s and usually Caucasian

Typically present with pruritis and eczematoid skin change on the vulva with well demarcation raised lesions on a red background often dotting with small pale islands

Invasive adenocarcinomas may occur in 4 - 17%

Synchronous neoplasms occur in 20-30% typically involving breast, colon, bladder, gallbladder, cervix, ovary, breast, uterus

Therefore need to exclude these - cervical smear, mammograph, colonoscopy, cystoscopy, abdomino pelvic imaging (USS or CT)

Book for surgical excision

24
Q

When is a DEXA scan indicated

A

Bone DEXA recommended for all women >65yrs AND younger postmenopausal women with one or more risk factors other than being white or menopausal;

Asian or Caucasian

Age

Previous hx fragility #

Family hx fragility #

Smoker

Low BMI

Family hx osteoporosis

Amenorrhoea

Calcium or vit D deficiency

Use of bone losing meds

Sedentary lifestyle

Excessive use of alcohol

Rheumatoid arthritis

Early menopause

25
Q

Surgical principles of vulvar paget’s

A

Wide excision of lesion or vulvectomy

2 cm margin preferred

Primary closure of vulva if too large then use flaps or skin graft

Intraoperative frozen section on lines of excision (accuracy associated with this is poor ~30%)

Preserve midline structures if feasible

Needs follow up 3 -6 monthly as recurrence is common (30-50%). Recurrence usually requires further surgery.

Also needs regular ongoing surveillance for synchronous tumours

26
Q

Management of a vaginal hematoma post op

A

Aim to manage conservatively in the first instance

Recatheterise and replace vaginal packing for tamponade

Commence broad spectrum antibiotics

Administer TXA 1g IV

TEDS and SCDS

Reassess in 1-2 hours

Surgical management in form of EUA + evacuation of haematoma if haemodynamically unstable from suspected ongoing blood loss or sepsis needing source control

27
Q

TVT

A

Preop – anaesthetic rv, HCG neg, preop bloods, safety checklist, IV abs, IDC, VTE prophylaxis, anaesthetic

Position patient in lithotomy

Identify urethra and infiltrate local anaesthetic subcutaneously to achieve hydrodisseciton

Make a 1cm horizontal incision 1-2 cm proximal to urethral meatus

Blunt dissection should be performed lateral to this incision on each side

Trochar should be introduced through the incision, aiming for the retropubic space and ‘hugging’ the pubic bone in order to avoid the bladder, and should then exit through the skin. Repeat on the other side.

Tension of tape should then be adjusted, ends should be trimmed/ trochars cut off

Vaginal mucosa closed over the top of tape

Cystosocpy performed

Postop - Document, VTE prophylaxis & GOPD 6 weeks

28
Q

Feacal incontinence

A

Rectal exam = to feel sphincter bulk and tone 

Referral to Colorectal surgeon, consider endoanal USS and nerve conduction studies

29
Q

Vaginal hysterectomy

A

Preop – anaesthetic rv, HCG neg, preop bloods, safety checklist, anaesthetic, IV abs, IDC, VTE prophylaxis,
Position in dorsal lithotomy
Grasp anterior lip of cervix with valsallum.
Infiltrate cervix with dilute local anaesthetic with adrenaline – circumferentially at junction of vaginal mucosae and cervix.
Make circumferential incision around cervix,
Dissect anterior to reflect bladder and repeat at posterior aspect to enter the para rectal space.
Perform an anterior and posterior colpotomy to enter the uterovesical and POD space.
Clamp, cut and tie off uterosacral ligaments bilateral – leave tie long.
Skeletnise the uterine vessels, clamp, cut and ligate bilateral, and repeat with the ovarian ligaments. Remove specimen. Assess haemostasis.
Secure uterosacrals to posterior aspect of vaginal vault. The vault is closed.
Postop - Document, VTE prophylaxis & GOPD 6 weeks

30
Q

Sacrospinous Fixation

A

Posterior vaginal wall is opened in the midline as for posterior repair.

Right pararectal space entered to access the ischial spine. Blunt dissection and lateral sweeping movements used

cardinal ligament containing the ureter retracted anteriorly

Sacrospinous ligament identified and exposed

A permanent or delayed absorbable suture is placed in the mid portion of the sacrospinous ligament 2-3cm medially from the ischial spine using the Capio needle

Repeat with second suture if unilateral procedure. Repeat same procedure on the opposite side if bilateral procedure.

Suture secured to the under surface of the vaginal vault or cervix and tied to reduce prolapse. Permanent suture material must be buried

Vaginal mucosa closed with continuous locked suture

PR examination performed

Vaginal pack and IDC are placed

31
Q

Posterior Repair

A

An incision is made to the posterior wall of the vagina.
Dissection below the vagina identifies the rectovaginal fascia and opens the space between the rectum and the pelvic floor muscle to the sacrospinous ligaments.
Defects in the fascia are corrected by centrally plicating the fascia using sutures.
The stitches can strengthen your tissues in two ways: first, by closing any tears, and second, by encouraging scar tissue to build in the area for extra support).
If necessary, the perineum will be repaired with deep stitches into the muscle.
The vaginal incisions are closed with stitches and the vagina may be packed with gauze.

32
Q

Modified Oxford Scale pelvic floor muscle tone

A
The Modified Oxford Scale (MOS) was used to rate pelvic floor muscle contraction on a scale of 0–5
0 = no contraction; 
1 = minor muscle 'flicker'; 
2 = weak muscle contraction; 
3 = moderate muscle contraction; 
4 = good muscle contraction 
5 = strong muscle contraction.
33
Q

Sacrocolpopexy

A

Sacrocolpopexy is performed either through an abdominal incision or ‘keyholes’ under general anesthesia.
The vagina is first freed from the bladder at the front and the rectum at the back.
A graft made of permanent synthetic mesh is used
to cover the front and the back surfaces of the vagina. The mesh is then attached to the sacrum (tail bone). The mesh is then covered by a layer of tissue called the peritoneum that lines the abdominal cavity; this prevents the bowel from getting stuck to the
mesh.

34
Q

Colpocleisis

A

Colpocleisis involves the removal of vaginal epithelium and subsequent imbrication of the vaginal muscularis in anterior-to-posterior apposition, thereby creating a tissue septum of support.
